Introduction

Adafruit CircuitPython module for the LSM303AGR’s 3-axis magnetometer

Dependencies

This driver depends on:

• Adafruit CircuitPython

• Bus Device

• Register

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Usage Example

import time
import board
import busio
import adafruit_lsm303agr_mag

i2c = busio.I2C(board.SCL, board.SDA)
sensor = adafruit_lsm303agr_mag.LSM303AGR_Mag(i2c)

while True:
    mag_x, mag_y, mag_z = sensor.magnetic

    print('Magnetometer (gauss): ({0:10.3f}, {1:10.3f}, {2:10.3f})'.format(mag_x, mag_y, mag_z))
    print('')
    time.sleep(1.0)

Building locally

To build this library locally you’ll need to install the circuitpython-build-tools package.

python3 -m venv .env
source .env/bin/activate
pip install circuitpython-build-tools

Once installed, make sure you are in the virtual environment:

source .env/bin/activate

Then run the build:

circuitpython-build-bundles --filename_prefix adafruit-circuitpython-lsm303agr-mag --library_location .

python3 -m venv .env
source .env/bin/activate
pip install Sphinx sphinx-rtd-theme
